#310 – The relationship between testosterone and prostate cancer, testosterone replacement therapy, and tools for predicting cancer aggressiveness and guiding therapy | Ted Schaeffer, M.D., Ph.D.View the Show Notes Page for This Episode Become a Member to Receive Exclusive Content Sign Up to Receive Peter’s Weekly Newsletter Ted Schaeffer is an internationally recognized urologist specializing in prostate cancer and a returning guest on The Drive. In this episode, Ted provides insights into the role testosterone plays, or doesn’t play, in the initiation and progression of prostate cancer. He unpacks the findings and limitations of the recent TRAVERSE trial, exploring the complex relationship between testosterone and prostate cancer. Ted delves into the molecular nature of prostate cancer, explaining the androgen receptor saturation theory and the potential impact of testosterone on cancer growth. He also discusses the use of the Decipher test to predict cancer aggressiveness and guide targeted treatment.
